Im trying to upgrade my system but when I execute the command this happens:

plex@plex-server:~$ sudo apt-get upgrade
[sudo] password for plex:
Reading package lists...
Building dependency tree         
Reading state information... Done  
You may want to run 'apt --fix-broken install' to fix it.
The following packages have unmet dependencies: 
  libgail-3-0 : Depends: libgtk-3-0 (=3.22.30-1ubuntu4) but 3.22.30-1ubuntu1 is installed
  libgtk-3-bin : Depends: libgtk-3-0 (>= 3.22.30-1ubuntu4) but 3.22.30-1ubuntu1 is installed
E: Unmet dependencies. Run 'apt --fix-broken install' without packages (or specify a solution).

I have done update before and I've tried autoclean, autoremove, --fix-missing but it still doesn't work.

EDIT This is what I have in my sources.list file:

    Next time please use the code formatting and not the quote, since here all the line breaks are missing. Did you try what it suggests sudo apt --fix-broken install? Post its output here please – dadexix86 Oct 05 '19 at 12:03

Let's take a look at the key part of the error message:

Los siguientes paquetes tienen dependencias incumplidas: 
  libgail-3-0 : Depende: libgtk-3-0 (=3.22.30-1ubuntu4) pero 3.22.30-1ubuntu1 está instalado
  libgtk-3-bin : Depende: libgtk-3-0 (>= 3.22.30-1ubuntu4) pero 3.22.30-1ubuntu1 está instalado

It says that you are trying to upgrade newer packages with older versions. Read it again, playing close attention to the difference between the version numbers.

Let's use a handy apt tool to see which repository these packages came from:

$ apt cache madison libgtk-3-bin
libgtk-3-bin | 3.22.30-1ubuntu1 | http://us.archive.ubuntu.com/ubuntu bionic/main amd64 Packages
libgtk-3-bin | 3.22.30-1ubuntu4 | http://us.archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages

Oh look, BOTH packages are listed. One is in bionic, the other in bionic-updates.

So the system is complaining that it NEEDS the version from bionic-updates, but cannot install it.

Time to look at your sources in your Software & Updates control panel (or in /etc/apt/sources.list). Ensure that the repo for bionic-updates is present and enabled.

  • This is what I have in my sources.list. If I'm not wrong, bionic-updates should be enabled (I've deleted comented lines). deb http://es.archive.ubuntu.com/ubuntu/ bionic main restricted deb http://es.archive.ubuntu.com/ubuntu/ bionic-updates main restricted deb http://es.archive.ubuntu.com/ubuntu/ bionic universe deb http://es.archive.ubuntu.com/ubuntu/ bionic-updates universe – Ropiper Oct 05 '19 at 19:09
  • Please add new information to your original question, formatted properly, instead of burying it in comments. – user535733 Oct 05 '19 at 19:18
  • Did you remember to run sudo apt- update before upgrade? If so, did you get any update errors? – user535733 Oct 05 '19 at 19:19
  • Yes I updated before with no errors. – Ropiper Oct 05 '19 at 19:28

First try this command:

apt --fix-broken install

And then:

sudo apt update
